Presentation Transcript

  1. PC Application Development Environment • PC Based EPICS Application Development • Generic PC vxWorks targets

  2. PC Based Application Development • Databases • record / device / driver support code development • Visual Basic and others can be used to call CA Client API • CA server tool development • CA DDE server

  3. For IOC Application Development You Will Need • EPICS base version 3.13 binaries • GNU make • PERL • vxWorks

  4. Install FTP Server • NT4.0 WS includes FTP server in Microsoft Peer Web Services package • Install with start | control panel | network | services | add (as administrator) • rumor: after installing Microsoft Peer Web Server you must reinstall NT service pack 3?

  5. Configure FTP Server • allow non anonymous login • add a NT user with password • use this user and password in your target boot configuration

  6. FTP Server - Tornado Configuration Subtleties • set the FTP home to the directory where the vxWorks file resides and supply no path with the vxWorks file name when configuring the target boot OR • use the “tgtsvr -c” to set the location of the vxWorks image for the Tornado target server

  7. Other Tornado Subtleties • When calling “dbLoadRecords()” from the host based shell you may be required to use “@cd xxxx” instead of “cd xxxx” • I have had some trouble with the host/target symbol table synchronization (needs further investigation)

  8. vxWorks 5.3.1 Bare Minimum Component Set Required by EPICS IOC core

  9. Create Application Development Tree • Mostly identical in operation to UNIX application development tree • To create an example application tree from a dos shell type • perl f:\epics\bin\win32\makeBaseApp.pl -e -b f:\\epics

  10. Generic PC vxWorks targets (vxWorks pc486 BSP) • We boot to DOS/W95 first followed by vxWorks • most PC IO card vendors supply DOS or W95 based configuration utilities • We transfer the vxWorks boot image over NCSA DOS FTP package

  11. Generic PC BSP Configuration • Boot change is volatile in this BSP • All boot parameters are compiled into the boot image • Select Ethernet card type, IO address, and interrupt level

  12. Conclusion • EPICS IOC application development environment is nearly identical under UNIX and Windows • Generic PCs have been operational at LANL for several months now with no major problems
